Abstract (en)
[origin: WO2010062223A1] An implantable medical device (100) comprises an impedance processor (130) for determining impedance data reflective of the transvalvular impedance of a heart valve (11, 13, 15, 17) of a heart (10) during a heart cycle. The determined impedance data is processed by a representation processor (140) for estimating diastolic and systolic transvalvular impedance representations. A condition processor (150) determines the presence of any heart valve malfunction, such as valve regurgitation and/or stenosis, of the heart valve (11, 13, 15, 17) based on the estimated diastolic and systolic transvalvular impedance representations.
